In Blountville, Tennessee, the Barnwood Builders find a log cabin built in 1818, and Mark teaches the new crew how to scout log cabins.

For the first time ever, the Barnwood Builders travel to New Jersey to take down their clients' 1839 swing beam-style barn.

The Barnwood Builders head to Paris, TX, to turn an 1800s cabin into a bridal suite, but they suffer a setback when most of the logs are missing tags.

The crew returns to Texas to build a timber frame wedding chapel. Later, they visit a log chapel they helped build to celebrate its anniversary.
